WASTE-SULFITE-LIQUOR DISIN'FEGTANT.

To all whom it. may concern:

Be it known that I, CARLETON ELLIS, a

of Larchmont, in the county of Westchester and State of New York, haveinvented certain new and useful Improvements in Waste- SulfiteLiquorDisinfectants, of which the following is a specification.

'Ihis invention relates to antiseptic and disinfecting compositionsandhas for its object the production of a water-soluble, waterl liquor.

miscible or easily water-emulsifiable preparation containing creosote.To this. en I combine the creosote with fairly concentrated wastesulfite cellulose liquor, with which it forms a seemingly homogeneousliquid that has the property of mixing readily with a large amount ofwater.

In preparing my composition I take waste sulfite liquor and neutralizeand concentrate, preferably under diminished ressure, to produce aclear, thick liquidof about 1.3 specific gravity. Coal tar creosote of as ecific gravity of about 1.1 and substantia 1y insoluble inwater isthen beaten into the sulfite liquor in the proportion of one volume ofcreosote to two volumes of the concentrated sulfite The resultingmixture does not ordi narily have the opaque, muddy appearance of anemulsion but is rather clear except for the brown coloration imparted bythe sulfite liquor. It therefore appears that the creosote combines tosome extent at least with some of the bodies present in the sulfiteliquor os'sibly with the main constituent,

calcium. 'gnosulfonate. Similarly Wood cre-' osote may be incorporatedwith concentrated sulfite liquor. With either creosote the proportionsmay be varied within wide limits, not only as regards the ercentage ofcreosote in the final product ut also with reference to theconcentration of the waste sulfite liqIuIpr. 1 using the illustrativeformula: set forth above I generally prefer to dilute largely withwater, say in the proportion of one quart Specification of LettersPatent.

The effectiveness of the creosote as a disinfectant is enhanced throughits incorporation with said liquor, presumably due to quasicombinationwith some of the elements of the liquor thereby permitting of a moreintense bactericidal action than normally prevails.

'sinfected is imthe diluted mix- Creosotes of various sorts may be usedbut I prefer to use only those which are substantially free from tar ortarry matter. Other bodies and disinfectants maybe added to the allonsof water.

composition such for instance as calcium or magnesium chlorid, magnesiumacetate, formaldehyde, starch, casein, etc. to give greater body orslower drying properties or special disinfecting action.

What I claim is 1'. A composition of matter consisting of two partsconcentrated waste sulfite cellulose liquor and one part creosote. A

. 2. 'A composition of matter consisting of concentrate waste sulfitecellulose liquor and coal tar creosote; the liquor being present in.substantially greater proportion than the creosote.

3. A disinfecting com osition comprising concentrated waste sul tecellulose liquor and creosote.

4. A disinfecting composition comprising liquor and creosote; the formerpresent in excess.

5. A disinfecting composition comprising waste sulfite cellulose liquorof about 1.3 specific gravity and creosote of about 1.1 specificgravity, the former present in excess.
